NITED STATES PATENT OFFICE SAMUEL WILLIAMSON, OF CINCINNATI, OHIO, AND GEORGE HOIRNUN G,

OF NEWPORT, KENTUCKY.

IMPROVEMENT IN HYDRANT STOP-BOXES.

Specification forming part of'Letters Patent No. 148,102, dated March 3, 1874; application filed December l5, 1873.

To all whom it may concern:

Beit known that we, SAMUEL WILLIAMSON, of Cincinnati, Ohio, and GEORGE HORNUNG, of Newport, Kentucky, have 'invented certain Improi-*enients in Hydraut Stop Boxes, of which the following is a specification:

Herctofore hydrant or gas stop-cool; boxes have been constructed with a cover either loosely attached by means of lugs hooking beneath the top flange of the box or by a hinge allowing the saine to lie loosely on the box, owin g to which they are often tampered with by unauthorized persons.

Our invention consists, Erst, in locking the lid onto the box, so that it cannot be opened without the key; and, second, in apeculiar arrangement of parts for accomplishing this purpose.

In the drawings, Figure l is a plan view of our invention, showing the lid and box separated. Fig. 2 is a sectional view, showing the cover and box when locked.

A is the hydrantbox, which is constructed in the usual nianner. Bis the cover or lid,

having on its upper surface the nut-cavity C, and cast on its under side the hollow guide D. Guide D is perforated at the end to allow the screw E to pass through, and on either side has an oblong aperture, through which the arms of the cross-bar F project. The screw E has a head, G, upon which the key H lits. The screw E is used to draw the ends of the cross-bar up against the inner flange I, and thereby hold the cover rinly in position. The cover has lugs K K K on its under surface projecting within the riin of the box.

rlhe arrangement above described furnishes the inea-ns of readily adjusting the cover lirnily to the box. It is lirst placed on the box, the ends of the cross-bar passing through the spaces between' the parts of the inner flange I, then is turned through an angle of ninety degrees, more or less, when the cross-bar, owing to the fact that it is held in place by the hollow guide D, is turned also, the ends thus coming under the flange I. The screw is then turned by onto the box. Any other equivalent forni of key may be used. The screw we generally niake of brass, as least liable to rust, out any other suitable metal may be used. rlhe guide or cross-bar may be slightly varied in shape, if desired.

Though this box-cover is intended for water, yet it may be just as successfully used for gas, and, by slight variations, 'it may also be used for the oil-boxes forear-axles, &c.

What we claiin is l. A locked hydrant-box, constructed with flange I, cross-bar F, internal screw, raising and lowering said cross-bar, and operated and locked by cap II, and cover B, cast with loose guide D upon its under side, so constructed and arranged as to operate the cross-bar F, substantially as and for the purpose hereinbefore set forth.

2. rEhe combination of cross-barF with cover B, when cast with guide D upon its under side, said guide having apertures to receive said crossbar, and being so constructed as to operate the saine, substantially as hereinbefore set forth.

3. The combination of cross-bar F and cover B, when cast with' guide D upon its under side, said guide having apertures to receive said cross-bar, and being so constructed as to operate the saine, with internal screwE, substantially as shown, and for the purpose hereinbefore set forth. p
